This book is a personal portfolio collaborated with China Light Industry Press.

It is not only an artwork collection, but also contains my personal experience over past 7 years. The 50°N in the title is lalitude of the UK and Switzerland, which have the largest proportion of the book.

In this book, I reviewed the changes of my art style and inner journey. My brushes have followed in my footsteps through England, Switzerland, the United States, and Japan. And I have tried different materials and techniques for different countries and regions, which have been influenced by each of my unique experiences during my travels.
